The new simple preset manager allows for easy browser and file management of the 128 presets that come with Świerk. 50 of which have been created by several excellent sound designers.

Świerk was chosen for OSC64. All the track s below were entered into the competition and created using only Swierk as the sound source.

"Although Świerk is not reinventing the wheel, it is a convincing virtual analogue synthesizer with simple operation, and a voluminous, good-natured character. A great-sounding and resource-saving weapon for analogue standards."
